Here, the target signal is a synchronization signal block (SS block), RMSI, message 2 (Msg2) in the random access process or message 4 (Msg4) in the random access process. The common downlink control channel is a common PDCCH (common Physical Downlink Control Channel). The resource set can be understood as a resource for transmitting the common downlink control channel.

Further, as the relationship between the resource set and the target signal, the resource set and the target signal, there is a specific relationship to the resources to be occupied, the resource set is indicated by the target signal, in the resource set There is a specific relationship between the beam used for the transmission of the common downlink control channel and the beam used for the transmission of the target signal, and the resource set has a specific relationship with the target signal which is predefined by the protocol. Although a relationship exists, this is not limiting in the embodiments of the present disclosure. Further, it may be understood that the user terminal can identify the resource set from the target signal as a relation between the resource set and the target signal.

Upon receiving the target signal, the user terminal can specify the resource set, and further can receive the common downlink control channel transmitted from the network-side device using the resource set. And the resource set can be explicitly or implicitly specified.

In the above method, since the resource set for common downlink control channel transmission is associated with the target signal, it is possible to flexibly adjust the resource for downlink control channel transmission based on the target signal. The flexibility of control channel transmission can be improved. Further, since the resource set for common downlink control channel transmission is associated with the target signal, the user terminal can specify the resource set from the target signal. Thus, the user terminal can receive the downlink control channel and save transmission resources, power consumption of the user terminal and the network side device without requiring omnidirectional transmission and beam scanning from the network side device. Moreover, it is also possible to transmit the common downlink control channel by multiple beams.

In the embodiment, since the common downlink control channel and the synchronization signal block occupy the same OFDM symbol, the user terminal directly uses the common downlink control channel in the OFDM symbol that receives the synchronization signal block. The power consumption of the user terminal and the network side equipment can be reduced because the beam scanning is reduced or not required while the flexibility of receiving and common downlink control channel transmission is improved.

In some selectable embodiments, the time-frequency resource occupied by the resource set and the time-frequency resource occupied by the synchronization signal block are FDM.

In this embodiment, it is realized that the time-frequency resource occupied by the resource set and the synchronization signal block is FDM. That is, the same OFDM symbol is occupied by the resource set and the synchronization signal block, but different frequency domain resources are occupied in the frequency domain, so that network resources can be saved.

In some selectable embodiments, the common downlink control channel and the synchronization signal block are transmitted on the same beam in the same OFDM symbol.

In the embodiment, since it is realized that the common downlink control channel and the synchronization signal block are transmitted by the same beam, the transmission performance of the common downlink control channel is improved, and the user terminal uses the same beam. Beam training and beam switching may be reduced by receiving the common downlink control channel and the synchronization signal block.

In some selectable embodiments, all content of the resource set configuration information is predefined by a protocol, or some or all of the resource set configuration information is defined in the synchronization signal block. It is set by our MIB.

In the embodiment, it is realized that the setting information of the resource set is predefined by the protocol, so that the signaling overhead can be reduced. Further, since it is also possible to set a part or all of the content of the resource set configuration information by the MIB, it is possible to improve the flexibility of the resource set.

From the above setting information, the user terminal can correctly specify the setting of the resource set and can correctly receive the common downlink control channel. Further, the candidate resource (candidate) may be referred to as a candidate position.

For the embodiment introduced above, in which the OFDM symbol occupied by the resource set and the OFDM symbol occupied by the synchronization signal block are the same, refer to the examples of FIGS. 3 and 4. In the example, the common downlink control channel is associated with SS block. The OFDM symbol occupied by the resource set (CORESET) transmitting the common downlink control channel is the same as the OFDM symbol occupied by SS block, and the time frequency resource occupied by the resource set and the time frequency resource occupied by SS block are the same. Is FDM. The common downlink control channel and the corresponding SS block have the same beam direction used for transmission and the same transmission cycle. Please refer to FIG. 3 or FIG. It is assumed that the number of SS blocks included in one synchronization signal block group (SS block burst) is 2, the transmission cycle N of the SS block is 20 slots, and the length of the slot is 14 OFDM symbols. .. According to FIG. 3 or 4, CORESET for common downlink control channel transmission has the same time domain position as the SS block time domain position, but different frequency domain positions. In the figure, the common downlink control channel transmitted by CORESET1 and SS block1 are transmitted by the same beam, and the common downlink control channel transmitted by CORESET2 and SS block2 are transmitted by the same beam. The transmission cycle of the common downlink control channel is the same as SS block.

Also, in this example, common downlink control transmitted by CORESET, such as CORESET resource allocation (of a fixed size and located on one or both sides of the frequency domain of SS block), mapping rules, DMRS pattern used, etc. The relevant parameters of the channel are predefined by the protocol.

Alternatively, the setting information of CORESET is notified by the MIB. For example, the size of the time-frequency domain resource occupied by CORESET and the offset value for the resource occupied by SS block are notified. In such a case, the user terminal must first correctly receive the MIB, analyze the setting information of CORESET, and further detect and receive the common downlink control channel with the same beam as SS block. The user terminal uses the common downlink control channel in the beam occupied by the corresponding SS block at the time domain position where the SS block appears, the resource position set by the parameter defined in advance, or the resource position notified from the MIB. Detect and receive.

In some selectable embodiments, the resource set configuration information is specified pre-defined by the synchronization signal block and/or protocol.

Here, the setting information may include all or part of the content of the setting information described in the above embodiment, and may further include time domain information of the resource set. The time domain information has a specific relationship with the time domain position occupied by the sync signal block.

In the embodiment, since the setting information is specified by the synchronization signal block and/or the protocol in advance, the user terminal specifies the resource set from the content predefined by the synchronization signal block and/or the protocol. , And can also receive a common downlink control channel. In addition, the user terminal can detect and receive the common downlink control channel in the resource set when the setting information is specified in advance by the protocol or the MIB. Further, the resource set can be specified based on the setting information, and the common downlink control channel can be detected and received by the resource set.

In some selectable embodiments, one synchronization signal block corresponds to a resource set for at least one common downlink control channel transmission, and the configuration information is specified by a MIB of the synchronization signal blocks. Statically and/or implicitly indicated, or there is a predefined relationship between the configuration information and the synchronization signal block by the protocol.

Here, the explicit instruction by the MIB means that the instruction information for instructing the setting information is included in the MIB. For example, the beam related parameter QCL of the sync signal block indicates a specific relationship between the DMRS of the common downlink control channel and the sync signal block. Therefore, the user terminal can specify the resource set from the synchronization signal block. Alternatively, the implicit instruction means that there is a predetermined relationship between the setting information and the setting information of the resource used for the MIB transmission. For example, the common downlink control channel period is the same as the MIB period, or the beams used are the same. That is, the user terminal can specify the setting information of the resource set from the MIB, and the overhead of the MIB can be saved by the implicit instruction. The fact that the setting information and the synchronization signal block have a relationship defined in advance by the protocol means that the setting information and the setting information of the resource occupied by the synchronization signal block are defined in advance by the protocol. Is to exist.

In the embodiment, the setting information is explicitly and/or implicitly indicated by the MIB of the synchronization signal block, or the setting information and the synchronization signal block are in a predefined relationship by a protocol. Exists. Therefore, the flexibility of the resource set can be improved.

In some selectable embodiments, the MIB of one sync signal block signals the time-frequency position of the resource set for at least one common downlink control channel transmission corresponding to the sync signal block.

In this embodiment, since the time-frequency position of the resource set is notified by the MIB, it is possible to further improve the flexibility of the common downlink control channel.

In some selectable embodiments, one sync signal block corresponds to a time frequency position of a resource set for at least one common downlink control channel transmission. Here, one synchronization signal block and at least one common downlink control channel transmission resource set corresponding to the synchronization signal block are located in the same slot, and the at least one common downlink control channel transmission is set. Resource set of is located before the sync signal block. Alternatively, one synchronization signal block and at least one common downlink control channel transmission resource set corresponding to the synchronization signal block are located in the same slot, and at least one common downlink control channel transmission A resource set is located after the sync signal block. Alternatively, one synchronization signal block and at least one common downlink control channel transmission resource set corresponding to the synchronization signal block are located in the same OFDM symbol in the same slot. Alternatively, at least one common downlink control channel transmission resource set corresponding to one synchronization signal block is located in one or more slots other than the slot transmitting the synchronization signal block. Alternatively, one synchronization signal block and at least one common downlink control channel transmission resource set corresponding to the synchronization signal block have the same occupied frequency domain resources.

In the embodiment, it is realized that one synchronization signal block corresponds to a time frequency position of a resource set for transmission of at least one common downlink control channel. That is, the user terminal can identify the time-frequency position of the resource set for transmitting at least one downlink control channel from one synchronization signal block, and can receive at least one common downlink control channel. Further, the relationship between one synchronization signal block and the corresponding at least one slot can be realized to further improve the flexibility of common downlink control channel transmission. Also, the relationship between the synchronization signal block and the resource set described above may be defined in advance by a protocol and set in advance by a user terminal.

In this embodiment, the fact that the synchronization signal block and the resource set occupy the same frequency domain resource may be realized in association with the above-described limited slot position. For example, at least one common downlink control channel transmission resource set corresponding to one synchronization signal block is located in one or a plurality of slots other than the slot transmitting the corresponding synchronization access block, and one synchronization The frequency domain resources occupied by the signal block and the resource set for transmitting at least one common downlink control channel corresponding to the synchronization signal block have the same frequency domain resources. Further, the one synchronization signal block and the resource set for transmission of at least one common downlink control channel corresponding to the synchronization signal block have the same frequency domain resource occupied, and the frequency domain occupied by the resource set is the same. Signaling overhead can be reduced since there is no need to direct resources. The user terminal may receive the common downlink control channel on the same frequency domain resource among the corresponding time domain resources based on the frequency domain resource of the received synchronization signal block.

In the embodiment, the relationship between the synchronization signal block and at least one common downlink control channel transmission resource set corresponding to the synchronization signal block is notified by the MIB and is defined in advance by a protocol. However, this is not limiting in the embodiments of the present disclosure.

In some selectable embodiments, the period of the resource set for at least one common downlink control channel transmission corresponding to one sync signal block is signaled by the MIB of the sync signal block or pre-specified by the protocol. Is defined in.

Here, since the period of the resource set for transmission of the common downlink control channel is notified by the MIB or is predefined by the protocol, flexibility of the common downlink control channel can be further improved.

In some selectable embodiments, the beam used to transmit the common downlink control channel and the beam used to transmit the corresponding sync signal block are the same, or the common downlink control channel is the same. The beam used for the transmission of each is indicated by the MIB of the corresponding sync signal block.

In the embodiment, since the beam used for transmission of the common downlink control channel and the beam used for transmission of the corresponding synchronization signal block are the same, the user terminal transmits the common downlink control channel and the synchronization signal block. The same can be received on the beam and beam switching can be reduced. Further, since the beam used for transmission of the common downlink control channel is designated by the MIB of the corresponding synchronization signal blocks, it is possible to transmit the synchronization signal block and the common downlink control channel by different beams, In addition, the user terminal can receive the synchronization signal block and the common downlink control channel on different beams to improve the flexibility of transmission.

Hereinafter, it will be described as an example that the resource set (CORESET) and related parameters for common downlink control channel transmission are designated by the MIB. The beam on which the common downlink control channel is transmitted may be the same as or different from the beam on which the corresponding SS block is transmitted. If the beam on which the common downlink control channel is transmitted is different from the beam on which the corresponding SS block is transmitted, the resource set (CORESET) and related parameters for transmission of the common downlink control channel are attached to the MIB. May be directed by. The CORESET for common downlink control channel transmission may be located before the time frequency domain resource occupied by the SS block or may be located after the time frequency domain resource occupied by the SS block. When setting the resource position of CORESET by the MIB, the resource may be set to CORESET within the same slot as that transmitting SS block, and one or more slots other than the slot transmitting the corresponding SS block may be set. The resource may be set to CORESET in the inside. In this example, it is assumed that one slot includes 14 OFDM symbols, and one SS block occupies 4 OFDM symbols.

The common downlink control channel transmission CORESET is located before the SS block, and at least one common downlink control channel transmission CORESET is set by the MIB of one SS block. As shown in FIG. 5, the different CORESET is TDM or FDM. The beam direction used for each CORESET may be the same as or different from the beam direction used for the corresponding SS block. Of course, one SS block may correspond to CORESET for transmitting common downlink control channels, and the CORESET for transmitting common downlink control channels may correspond to the same or different beam directions.

Also, CORESET for common downlink control channel transmission is located after SS block, and at least one CORESET for common downlink control channel transmission is set by the MIB of one SS block. As shown in FIG. 6, the different CORESET is TDM or FDM. The beam direction used for each CORESET may be the same as or different from the beam direction used for the corresponding SS block. Of course, one SS block may correspond to CORESET for transmitting common downlink control channels, and the CORESET for transmitting common downlink control channels may correspond to the same or different beam directions.

Also, CORESET for transmitting the common downlink control channel is located in one or more slots other than the slot transmitting the corresponding SS block, and at least one common downlink is provided by the MIB of the one SS block. Set CORESET for control channel transmission. As shown in FIG. 7, the different CORESET is TDM or FDM. The beam direction used for each CORESET may be the same as or different from the beam direction used for the corresponding SS block. Of course, one SS block may correspond to CORESET for transmitting common downlink control channels, and the CORESET for transmitting common downlink control channels may correspond to the same or different beam directions.

In some selectable embodiments, the bandwidth occupied by CORESET set by the MIB may be within the SS block transmission bandwidth, may be the same as the SS block transmission bandwidth, or may be equal to the SS block transmission bandwidth. The bandwidth may be other than the block transmission bandwidth, but the embodiment is not limited thereto.

In some selectable embodiments, some or all of the content of the configuration information of the resource set is an index of a configuration information table pre-defined in the protocol by the MIB of the sync signal block. A part of the setting information is notified by a MIB of the synchronization signal block, and the other part of the setting information is pre-specified by a protocol. Is defined in.

In the embodiment, since the setting information is indicated by the table index, the signaling overhead is reduced. Since it is realized that part of the setting information is notified by the MIB and the information of the other part is predefined by the protocol, the overhead of the MIB can be reduced. Some of the information notified by the MIB is information in which the setting information and the synchronization signal block have a certain relation, for example, related information such as frequency domain position and time domain position. Other content is predefined by the protocol. For example, CCE-to-REG mapping relationship, PDCCH-to-CCE mapping relationship, detection period and beam direction related information are all defined by the protocol.

In some selectable embodiments, the table index is an index of a combination of some or all of the content of the configuration information, or the table index is of some or all of the content of the configuration information. It is an index of the contents of each item.

Here, the fact that the table index is an index of a combination of some or all of the contents of the setting information may be understood as a collective instruction. That is, the contents of a plurality of items of the setting information can be designated by one index. Therefore, the length of the instruction bit field required in MIB is reduced as much as possible.

If the table index is the index of the contents of each item among some or all contents of the setting information, one index is set for the contents of each item. For example, resource set (CORESET) size, position, CCE-to-REG mapping relationship, PDCCH-to-CCE mapping relationship, common PDCCH transmission period, and QCL information for SS block are all indicated by a single index. To be done.

In some alternative embodiments, the size of CORESET may be a subset defined by the protocol (eg, CORESET with configuration 1 occupies N1 PRBs, M1 OFDM symbols, and CORESET with configuration 2). Occupies N2 PRBs and M2 OFDM symbols), the position of CORESET can be one position for SS block (eg, P OFDM symbols are separated in the time domain and Q PRBs in the frequency domain). The position of CORESET with respect to SS block has a plurality of candidate positions.).

Alternatively, there are A sets of size of CORESET, B candidate positions for SS block of CORESET, and CCE-to-REG mapping rules are centralized (localized) and distributed (distributed), The mapping rules of PDCCH-to-CCE are centralized (localized) and distributed (distributed), and there are C transmission cycles of the common PDCCH, and D pieces of QCL information for the corresponding SS block. For example, when A=2, B=2, C=4, D=4, finally, the parameters of the common downlink control channel are 2*2*2*2*4*4=256 in total. There are combinations, and it is necessary to transmit 8-bit information in MIB. Of course, the protocol may define that only one subset of all combinations needs to be indicated.

Of course, the number of parameters to be collectively instructed is not limited to the above six parameters, and other parameters to be notified can be collectively instructed and only some of the parameters can be collectively instructed (other parameters that do not require the instruction , Specified by the protocol in advance), but is not limited in the embodiments of the present disclosure.

For example, based on the above example illustrating that the resource set (CORESET) and related parameters for transmission of the common downlink control channel are indicated by the MIB, the bit information that can indicate the common downlink control channel in the MIB is , Should be as small as possible. In one embodiment, a plurality of setting information is instructed by a method of collectively instructing, that is, a combination of some or all contents is instructed. For example, the parameters related to the common downlink control channel include setting information of CORESET for common downlink control channel transmission, CCE-to-REG mapping rule, PDCCH-to-CCE mapping rule, and common downlink control channel There is a QCL parameter for a corresponding SS block of the common downlink control channel or the CORESET DMRS for common downlink control channel transmission, which is a period. A parameter setting information of the common downlink control channel can be instructed by introducing a collective instruction table into the protocol and instructing the table index. Specifically, suppose that the resource position of CORESET for transmission of the common downlink control channel has two types of candidate positions and sizes, and the mapping rule of CCE-to-REG has two types of mapping rules, localized and distributed. The mapping rule of the PDCCH-to-CCE has two types of mapping rules, localized and distributed, and the monitoring period (Common PDCCH occupation period) of the common downlink control channel is, for example, {two per slot. There are four types of QCL parameters for the SS block corresponding to the common downlink control channel or the DMRS of CORESET, and there are a total of 2*2*2*. There are 4*2=64 types of combinations, and a total of 6 bits of information is required to instruct. In some alternative embodiments, if only some of the parameters need to be indicated, eg if the CCE-to-REG and PDCCH-to-CCE mapping rules are defined by the protocol. As shown in Table 1, only 4 bits are required to instruct a combination of a total of 16 types of parameters.

For example, in the MIB, if the parameter setting instruction information of the common downlink control channel is 0000, CORESET for transmission of the common downlink control channel is the candidate position 1, the appearing period is P1, and the corresponding SS block is Indicates that the QCL parameter is Q1. Upon receiving the setting parameter, the terminal detects and receives the common downlink control channel on P1 and Q1 at CORESET candidate position 1.

As a special example, when the collective instruction information field in the MIB specifies that the resource setting of CORESET is candidate position 1, the detection period P1 is 2 slot, and the QCL parameter is Q1, common downlink control is performed. The channel transmission is as shown in FIG.

In some selectable embodiments, the protocol defines that some combinations of all combinations make up the parameter collective indication table of the common downlink control channel. Taking the above case as an example, there are 64 combinations in total, but if only some of the combinations are instructed in the protocol and, for example, only 15 of them are instructed, 4 bits of instruction information is attached in the MIB. And give instructions.

Here, the number of parameters of the common downlink control channel that need collective instruction is specified by the protocol. In the embodiments of the present disclosure, the number of parameters and the number of parameters that need to be specified are not limited.

In some selectable embodiments, only some of the parameters are batch indicated in the form of a table, other parameters are defined by the protocol or indicated by other information fields.

It should be noted that the MIB can be accompanied by a plurality of CORESET setting information, that is, a plurality of CORESET can be set for common downlink control channel transmission.

To transmit. For example, the user terminal can acquire the setting information of the second common CORESET from the related information attached to the RMSI. The RMSI is scheduled by the common downlink control channel transmitted on the first common CORESET. The beam used for transmission of the second common CORESET set by the RMSI is specified by the beam direction parameter attached to the RMSI, such as the SS parameter for the SS block received by the user terminal. The network-side device can set one or more second common CORESETs by the RMSI. The plurality of second common CORESETs may be TDM or FDM, and may be transmitted by the same beam or different beams.
